How to Keep Pipes From Freezing When Your Heater Fails
Protecting Your Home During a Heating Crisis
When the temperature drops below freezing and your furnace suddenly stops working, the clock starts ticking. Beyond the discomfort of a cold house, your biggest concern is the integrity of your plumbing system.

The Immediate First Step: Drip Your Faucets
The simplest and most effective way to prevent a pipe from bursting is to relieve the pressure. You do not need a heavy flow; a slow, steady drip is sufficient.
Focus on faucets located on exterior walls, as these are the most vulnerable to the cold. Opening both the hot and cold taps ensures that water is moving through both lines, which significantly reduces the chance of ice formation.
Open Cabinet Doors and Circulate Air
In most homes, kitchen and bathroom plumbing is tucked away inside cabinets. These enclosed spaces prevent the remaining ambient heat in your home from reaching the pipes.
Open all cabinet doors under sinks to allow the warmer air from the room to circulate around the plumbing. While your house is cooling down, that extra few degrees of indoor air can be the difference between a liquid and a solid pipe.
Focus on Vulnerable Areas
Pay close attention to pipes in unheated areas like basements, crawlspaces, or attics. If you have access to these areas, consider wrapping the pipes in towels or foam insulation if you have it on hand.
While you manage the cold, it is also important to consider safety. If you are using alternative heat sources, ensure you know how to test for carbon monoxide to keep your family safe from dangerous fumes.
Seal Air Leaks Near Plumbing
Cold air often enters the home through small gaps around dryer vents, electrical wiring, or windows. If a blast of sub-zero air hits a copper pipe directly, it will freeze almost instantly.
Use rags, towels, or even duct tape to temporarily seal these drafts. Preventing a direct wind chill on your plumbing is a high priority during a heating failure.
Maintain Your Water Heater
Your water heater acts as a large reservoir of thermal energy. In an emergency, ensuring this system is functioning correctly is vital.

Alternative Heating and Safety
While you wait for a technician, you may be tempted to use space heaters. Only use heaters that are UL-certified and never leave them unattended. Position them safely away from curtains and furniture.

Communication is Key
When you call for help, being clear about your situation can help the dispatcher prioritize your service. Be prepared to describe your system and the specific symptoms of the failure.
Reviewing tips for communicating with your HVAC company can help you provide the right details so they arrive prepared with the necessary parts.
When to Shut Off the Main Water Valve
If you notice that a pipe has already frozen (no water comes out of the tap) or if you see a crack in a pipe, you must shut off the main water valve immediately. This prevents the inevitable flood that occurs when the pipe eventually thaws.
Locate your main shut-off valve before an emergency happens. It is usually found near the water meter or where the main line enters the house.
